Fish Egg Test

One of the most reliable methods of assessing the effects of chemicals on fish reproduction and development is the fish egg test. The fish egg test is a standardized method for evaluating the toxicity of chemicals using fertilized fish eggs as the test organism. The test measures various endpoints including hatch success, embryo survival and abnormalities. The fish egg test is sensitive and reliable and provides information on the potential harm of chemicals to aquatic ecosystems.

CD BioSciences offers a comprehensive portfolio of toxicity, genetics and efficacy services. We challenge the discovery process by combining our expertise in fish biology with laboratory automation and artificial intelligence. CD BioSciences' mission is to accelerate research and allow for robust safety and efficacy evaluations of compounds for faster market access.

Our Services

Our scientists recommend fish egg testing with zebrafish to determine the acute toxicity of water components and sewage to fish embryonic stages. During the fish egg test, four apical observations are recorded as indicators of lethality:

• Coagulation of fertilised eggs observation
• Lack of heartbeat observation
• Lack of detachment of the tail-bud from the yolk sac
• Lack of somite formation observation

Course of the Fish Egg Test

• Fish eggs are tested by exposing fertilized eggs to different concentrations of chemicals or pollutants for specific periods of time.
• The treated eggs are then incubated under controlled laboratory conditions and monitored for hatch success, larval survival and malformations.
• Compare the test results to the control group and note any significant differences.

Our Advantages

• Our scientists only need to use a small number of samples to complete the fish egg detection, reducing the waste of samples.
• We combine our expertise with the use of automated equipment and data analysis solutions powered by AI, resulting in short test cycles and test results within days, saving researchers time.
• The test is also highly sensitive, providing information on the potential ecotoxicity of chemicals at sublethal concentrations.
